| grayscale | number | 0.0 | Converts the input image to grayscale. The value indicates the grayscale conversion ratio. If the input value is **1.0**, the image is converted into a grayscale image. If the input value is **0.0**, the image does not change. If the input value is between **0.0** and **1.0**, the effect changes in linear mode. The unit is percentage.<br>Value range: [0, 1]<br>**NOTE**<br>A value less than 0 evaluates to the value **0**. A value greater than 1 evaluates to the value **1**.<br>Since API version 9, this API is supported in ArkTS widgets.|
| brightness | number | 1.0 | Applies a brightness to the current component. The input parameter is a brightness ratio. The value **1** indicates no effects. The value **0** indicates the complete darkness. If the value is less than **1**, the brightness decreases. If the value is greater than **1**, the brightness increases. A larger value indicates a higher brightness.<br>Value range: [0, +∞)<br>**NOTE**<br>A value less than 0 evaluates to the value **0**.<br>Since API version 9, this API is supported in ArkTS widgets.|
| saturate | number | 1.0 | Applies the saturation effect to the current component. The saturation is the ratio of the chromatic component to the achromatic component (gray) in a color. When the input value is **1**, the source image is displayed. When the input value is greater than **1**, a higher percentage of the chromatic component indicates a higher saturation. When the input value is less than **1**, a higher percentage of the achromatic component indicates a lower saturation.

| Type| Description|
| -------- | -------- |
| and | The **and** operator is used to combine multiple media features into one media query, in a logical AND operation. The query is valid only when all media features are true. It can also combine media types and media functions.<br>For example, **screen and (device-type: wearable) and (max-height: 600)** indicates that the query is valid when the device type is wearable and the maximum height of the application is 600 pixel units.|
| not | The **not** operator is used to perform a logical negation for a media query. **true** is returned if the query condition is not met. Otherwise, **false** is returned. In a media query list, logical negation is performed only for the media query using the **not** operator.<br>For example, **not screen and (min-height: 50) and (max-height: 600)** indicates that the query is valid when the height of the application is less than 50 pixel units or greater than 600 pixel units.<br>You must specify the media type when using the **not** operator.|

| only | The **only** operator applies the selected style only when the entire expression is matched. It can be used to prevent ambiguity on browsers of earlier versions. The statements that contain both media types and media features produce ambiguity when they are received by some browsers of earlier versions. For example:<br>screen and (min-height: 50)<br>The browsers of earlier versions would mislead this sentence into screen, causing the fact that the specified style is applied when only the media type is matched. In this case, the **only** operator can be used to avoid this problem.<br>You must specify the media type when using the **only** operator.|
| ,(comma) | The **or** operator is used to combine multiple media features into one media query, in a logical OR operation. The query is valid if a media feature is true. The effect of a comma operator is equivalent to that of the **or** operator.<br>For example, **screen and (min-height: 1000), (round-screen: true)** indicates that the query is valid when the minimum height of the application is 1000 pixel units or the device screen is round.|

At MediaQuery Level 4, range query is imported so that you can use the operators including <=, >=, <, and > besides the max- and min-operators.
